Symbols and multipliers in Plenty of Jewels 20 Hot

To earn a win in Plenty of Jewels 20 Hot you need to have 3 or more identical symbols land on 5 reels in a row. The combination must begin with the leftmost reel and be formed on at least one of the 20 fixed paylines.

All symbols featured in the slot can be tentatively subdivided into regular ones and special ones. The first group consists of multi-coloured jewellery. With a line bet of 1 credit, they award you with the following prizes:

  • Orange gem: for 3 of theses pictures you earn 20 credits, for 4 – 80 and for 5 – 400
  • Blue and bright green gems: for 3 pictures you get 20 credits, for 4 – 40 and for 5 – 200
  • Pink, purple, and dark green gems: for 3 pictures you are paid 10 credits, for 4 – 20 and for 5 –100

The game features 2 special pictures:

The Wild is represented by a jewel in a gold frame. Once it comes up on the reels, it becomes a part of various combinations by substituting for any missing symbols on active paylines. In addition, the Wild can produce its own combinations with the following payouts:

  • For 3 symbols it pays you 50 credits, for 4 – 500 and for 5 – 2,000

The picture of the golden star is the Scatter symbol. It does not form any combinations on paylines, but it earns you the rewards for landing anywhere on the reels:

  • For 3 symbols on a line you earn 100 credits, for 4 — 400 and for 5 — 10,000
